There are probably more videos purportedly showing a leaked iPhone 6 than there are covers of Miley Cyrus' The Climb on YouTube by this point, but the latest could well be the real deal, showing a working smartphone which looks to be running iOS 8 and unlocks using the TouchID fingerprint scanner.

A Chinese video blogger shows off the handset against a blank screen in the video, which differs from less convincing leaks which are probably just "skinned" Android phones in that it appears to run on iO8, with a Health app icon, predictive text keyboard and a selfie timer on the camera being visible.
